2. 1. Preclinical PET imaging of Alzheimer's disease progression

   Author : Xiaotian T. Fang; Stina Syvänen; Dag Sehlin; Lars Lannfelt; Merja Haaparanta-Solin; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; transgenic mice; PET; antibody-based tracer; mGluR5; ABP688; di-scFv; amyloid-β;

   Abstract : Amyloid PET imaging with [11C]PIB enabled detection of Aβ for the first time in vivo. However, [11C]PIB is a small molecule that binds only the insoluble Aβ plaque. Rather, the soluble Aβ aggregates are considered the cause of Alzheimer’s disease (AD). READ MORE

4. 2. Characterization of [18F]flutemetamol binding properties : A β-amyloid PET imaging ligand

   Author : Kerstin Heurling; Mark Lubberink; Jens Sörensen; Julie Price; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography PET ; molecular imaging; amyloid; tracer validation; Radiology; Radiologi;

   Abstract : The criteria for diagnosing Alzheimer’s disease (AD) have recently been revised to include the use of biomarkers for the in vivo presence of β-amyloid, one of the neuropathological hallmarks of AD. Examples of such biomarkers are positron emission tomography (PET) β-amyloid specific ligands, including [18F]flutemetamol. READ MORE

5. 3. Multimodal Chemical Imaging of Amyloid Plaque Pathology in Alzheimer’s Disease

   Author : Wojciech Michno; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; beta-amyloid; electron microscopy; imaging mass spectrometry; lipids; luminescent conjugated oligothiophenes; matrix-assisted laser desorption ionization mass spectrometry MALDI-MS ; molecular imaging; nanoscale secondary ion mass spectrometry NanoSIMS ; neurodegeneration; peptides;

   Abstract : Alzheimer’s disease (AD) is the most common form of dementia. AD has been linked to the aggregation of amyloid beta (Aβ) peptides into extracellular deposits, Aβ plaques. These are also found in cognitively unimpaired amyloid-positive (CU-AP) individuals, but these Aβ plaques are primarily diffuse in structure. READ MORE

6. 4. Preclinical PET imaging and therapy of Alzheimer's disease

   Author : Silvio R. Meier; Stina Syvänen; Dag Sehlin; Greta Hultqvist; Matthias Brendel; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; amyloid-beta; positron emission tomography PET ; bispecific antibody; BACE-1; TREM2; GFAP; Molekylär medicin; Molecular Medicine; Neuroscience; Neurovetenskap;

   Abstract : The main histopathological hallmarks of Alzheimer’s disease are extracellular amyloid-beta (Aβ) plaques and intracellular neurofibrillary tangles, containing tau protein. Because of misfolded and aggregated proteins, activated microglia and astroglia react with a neuroinflammatory response, which may contribute to disease progression and severity. READ MORE

7. 5. Towards Clinical Implementation of Dynamic Positron Emission Tomography in Neurodegenerative Diseases

   Author : My Jonasson; Mark Lubberink; Lieuwe Appel; Jens Sörensen; Michel Koole; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET; Molecular imaging; Quantification; Kinetic modelling; Parametric images; Alzheimer’s disease; Parkinson’s disease; Radiology; Radiologi;

   Abstract : Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative disorders worldwide. Positron emission tomography (PET), together with suitable biomarkers, can aid in the clin-ical evaluation as well as in research investigations of these diseases. READ MORE
